SIZING AND NAILING BARREL-HOOPS.

5 SPECIFICATION forming part of Letters Patent No. 540,037, dated May 28, 1895.

Application tiled September 13. 1894.` Serial No. 522,876. (No model.)

To all whom it may concern.-

Be it known that I, LoUls WEIDMANN, a citizen of the United States, residing in the y city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Sizing and Nailing Barrel-Hoops, of which the following is a specification.

This invention has reference to an improved machine for sizing and nailing the hoops required for sugar, flour and other barrels, butter tubs, &c., so as to complete them preparatory to slipping them into position over the staves of the barrels or tubs, the machine facilitating the sizing and nailing of the hoops and permitting the use of unskilled in place of skilled hands for the work; and the invention consists of a machine for sizing and nailing barrel-hoops, which comprises a sectional and extensible gage-cylinder, means for adjusting the cylinder-sections to the proper size, a lever for retaining the overlapping ends of the hoop in position on the gage-cylinder, a second lever for retaining the lower part of the hoop in position on the same, and a fulcrumed lever for operating the lower sliding section of the extensible gage-cylinder until it is arrested by suitable stops, so as to set each hoop to proper size on the gage-cylinder preparatory to connecting the ends by the nails or staples usually employed, as will be fully set forth hereinafter' and finally pointed out in the claim.

In the accompanying drawings, Figure l represents a front elevation of my improved machine for sizing and nailing barrel-hoops. Fig. 2 is a vertical transverse section of the same on line 2 2, Fig. l, showing the parts `in position before the hoop is placed in locked position on the same; and Fig. 3 is a side elevation of my improved machine, showing the parts in position after the hoop is locked to the gage-cylinder adjusted to the proper size and ready for nailing. Y

Similar letters of reference indicate corre' sponding parts.

Referring to the drawings, A represents an upright supporting-frame, which is provided with parallel strengtheningribs A at the back of the upright-frame A. The upper part A2 of the frame A is made approximately of disk-shape, the upper part of the said disk carrying the semicircular stationary section B of an extensible. gage-cylinder B, which section is attached by screws b to r`the upper disk-shaped part A2 of the supporting-frame A. The lower semi-circular section B of the gage-cylinder :B is provided by a web b2, which is guided by slots b3 'on stationary headed studs b4 of the upper part A2, as shown in Figs. l and 2. The lower section B2 of the gage-cylinder B is connected with the stationary section B by helical springs b, the ends of which are connected respectively to the web b2 of the lower section of the gage-cylinder and to the upper stationary section of the gagecylinder. An opening a2 is arranged in the center of the upper part A2 of the supportingframe A, while the thicker or reinforced U- shaped central portion b5 of the web b2 of the lower section B2 of the gage-cylinder is guided along' the sides of the central opening a2,'asA shown in Fig. 1.

The hoop that is to be sized and nailed is placed first against the lower movable section B2 of the gage-cylinder B, its upper ends being bent so as to overlap each other on the stationary section B' of the same. As soon as this is accomplished, the treadle T, the lever t of which is pivoted to a backwardly extending bracket t at the lower part of the sup porting-frame A, is depressed by the attendant, said treadle-lever being connected by a helical spring t2 with the upper part A2 of the frame A, so as to return the treadle into raised position when released by the foot. A connecting-rod d is pivoted to the treadle-levert and to an intermediate lever D, which is fulcrumed to rearwardly-extending brackets d', of the upper part A2, the rear end of said lever being curved in upward direction and provided at its upper end with a fulcrumed arm D that carries at its upper end an anti-frictionV roller d2. The lower end of the arm D is adjustably connected by a helical spring d2 and screw-buckle d4 with a lug d5 attached to the curved lever D. The arm D is pro'- vided with an adjustable stop-screw d6 that passes through a lug (17 on said arm, so that the latter cannot be moved beyond the position shown in Fig. 2, which is the normal position of the arm D. The anti-friction-roller d2 engages the cam-shaped rear end E of a retaining-lever E, that is fulcrumed to up- IOO Wardly-extending brackets e of the upper part A2 of the supporting-'frame A, the front end of the retaining-frame being made in the shape of a hook that is adapted to engage and press the overlapping ends of the hoop on the upper section B of the gage-cylinder, as shown in Fig. 3, when'th'e anti-friction roller d2 ofthe pivot-arm D is passed under the cam-shaped rear end E of the fulcrumed lever E, as shown in Fig. 3. A second retaining-lever F is fulcrumed to a lug f attached to the lower front part of the frame A .and

actuated by an anti-friction roller f on ther treadle-lever t, which roller engages 'the lower curved end of the fulcrumed lever F, so that when the treadle is lowered, the upper end of `the same is enabled. to press on the lower part of the hoop and retain thesa'm'e in position on the lowerjseotion of the vgage-cylinder, as v shown in Fig. V3.

The lower end of the fnlcrumed retaininglever F is arrested by thehfead offa stop-screw f2 when the upper end of the lever t .arrives at the proper position for retaining thehoop. The front end of the intermediate curved'and fulcrumed lever D is also provided with antifriction roller dx, lwhich extends into the vrecess ot the U-shaped center portion b5 ofthe web b2 of the movable section B2 rof the ,gagecylinder. When the front end of the lever D'arrives at its lowermost position, its antifriction roller dx. engages'the movable-'section B2after the retaining-levers E and F have engaged the hoop'and llocked the-saine in position on the gagecylinder. By the action of the front end of the curved lever D on the-movable section B2 of the ,gage-cylinder, -saidsection is moved in Idownward directionalong its guidestuds b4, so` that the'hoop is extendedto the size to which the sections B B2 of the gage'cyli'nder are adjusted. The movablesectio'nfB2 is provided with 'stops g `which ext'endthrough slots g in the upper partA2 to therearof the latter and which abut against stop-screws g2, passing through lugs g2=at the rear of the upper part A2 when .the sect-ion A2-is lowered, so as to arrest the downward ymotion of the same, and set the hoop to the'exact size required. The overlapping ends of 'the hoop are then ready for being vnailed and stapled in the usual'manner, after which the treadle is released, so that the hoop can'be removed,

owing to the returnof the movable section B2 of the gage-cylinder to its'initi'al position by its 4spring t', and the receding motion of the retaining-levers 'E-and F. Thelower section of the Ygage-cylinder canbe adjusted within certain limits, so that one and the same machine can be used for setting barrel-hoops of dierent sizes.

For making vallsizes ofsugar, flour and other barrels, two or three sizes of machines are sufficient. By the `motion of the treadle, and the action of the intermediate actuating mechanism, the motion of the different levers is so timed that the hook of the retaining-lever E engages the first upper overlapping ends of the hoopand holds the same in position on the stationary section of the gage-cylinder, while the lower retaining-lever F retains next the lower part of the hoop and holds it until the downward motion of the movable section of thegage-cylinder is completed and the hoop extended to its proper size, said downward 'motion being `accomplished by the downward lmotion of the front end of the intermediate lever D, and its engaging of the lower part of the rU-shaped center portion b5 of the movable section B2 bythe anti-friction roller dx. The lower section B2 of the .gagecylinder B is thereby moved into proper position, until its stops g abutlagainst the stop-screwsat the rear of the upper :part A2 of the frame A, as before mentioned.

By my improved machine, the sizing and nailing of barrel-hoops `are facilitated and expedited and considerably cheapened, for the reason that the machine can be operated by cheaper labor than theskilled labor heretofore required for doing this kind of work.

I-Iaving thus described my invention, I claim as lnew and desire to secure by Letters Patent- In ama-chine for sizing'and nailing barrelhoops, anluprightsupporting-frame having a disk-shaped uppervpartfa gage-cylinder applied tothe latter and composed of a station-ary upper-section kand a shiftable lowersectionguid'ed on the disk-shaped upper part of -the supporting-frame, a retaining-lever having a lhook-shaped forward vend extending beyond the gage-cylinder, said lever being fulcrnmed-to `the `upper part of the supporting-frame. above the iixed'section of 'the gage-cylinder, a-retaining-lever fulcrumed in front of the supporting-frame, below the shiftable lower-section, the hook-'shaped end of said upper lever being adapted to engage the overlapping ends of the hoop, and with the face of the fixed section of the gage-cylinder, and vsaid lower lever being adapted to engage the middle-portion lof the hoop, and means forfactuatin g said levers,l substantially asset forth. y

iIn testimonythfat I claim'the foregoing as myiinvention I have signed my name inpresence of two subscribing Witnesses.
